New chiral derivatizing agents have been prepared through a simple, short-step synthesis. The absolute configuration of α-chiral carboxylic acids can be assigned on the basis of the NMR chemical shift difference between diastereomeric esters. Because of the modular structures of the agents, the anisotropic effect could be easily manipulated to afford large chemical shift differences even in polar solvents
通过简单,短步的合成已经制备了新的手性衍生剂。α-手性羧酸的绝对构型可以基于非对映体酯之间的NMR化学位移差异来分配。由于试剂的模块化结构,即使在极性溶剂中,也可以轻松控制各向异性效应,以提供较大的化学位移差异。
